- a. maar IMPROVEMENT IN BUILDINGS.

Specification forming part of Letters Patent No. l92,44l, dated June 26,1877 application filed April 16, 1877.

To all whom 'it may concern:

Be it known that I, ADAM W. LoU'rH, of Philadelphia, Pennsylvania, haveinvented a new and useful Improvement in Buildings, of which thefollowing is a specification:

My invention relates to an improvement in. the construction of buildingsin which noxious odors are generated, such as bone-boiling orfat-rendering establishments, printing-ink factories, Src. the object ofmy invention being to prevent the escape of the' odors from the buildingexcepting through a particular outlet.

This object I attain in the manner which I will now proceed to describe,reference being had to the accompanying drawing, in which- Figure lis alongitudinal section of my improved building; Fig. 2, a transversesection of the same; Fig. 3, a sectional plan; Fig. 4, an enlargedsection of a portion of the building; and Figs. 5 and 6, views of amodilication. Y

The building shown in Figs. 1, 2, and 3 has inner and outer walls,A andB, between which intervenes a chamber, D. The inner wall incloses tworooms, E and F, arranged one above the other, and each having doubleceilings, which inclose spaces en At one end of the building is achimney, I, which communicates with the rooms E and F through open ingsb, with the space D through openings d, and with the spaces a throughopenings e. In the outer wall A are the usual door-openings j' andWindow-openings t', similar openings being arranged in the inner Wall B,in order to furnish light and permit access to the rooms. The openings fare provided with doors of a character described hereinafter, and thewindowopenings in the outer wall are provided with sashes, as usual; butthe openings in the inner wall are preferably unobstructed, in order toallow free communication between the rooms E and F and the space D.Additional communication between the rooms and space D is afforded byperforations g in the wall B, while communication between the room-s andthe spaces a in the hollow ceil-` ings is permitted' by perforations m.i

The natural draft of the chimney I issufficient to cause a partialvacuum therein, as

well as in the space D between the walls A and B, and in the spaces ctin the ceilings, so thatthere is a constant tendency of the noxiousodors in the rooms E and F to escape either into the chimney directly orelse into the spaces D or a, and thence to the chimney, When the vaporsare collected in the chimney they may be readily destroyed or renderedinnoxious before being allowed to escape. Fresh airis preferablyadmitted to the building through a tunnel, H. (See dotted lines, Fig.1.)

Thedoors J of my improved building are made double, and consist of innersliding sections n a and outer 1sliding sections s s', the inner andouter sections of the door being independent of each other, so that aperson desirous of leaving the building may first open the inner sectionand close it behind him before opening the outer section, thus preventing odors from the room escaping into the outer air. I prefer to makethe inner section of the door of the box-like form shown, and toperforate it, so that the space inclosed by it may communicate with thespace D and with the room E, odors from which may thus escape throughthe door into the space D even when the door is closed.

' In applying my invention to a building with but a single Wall, as inFigs. 5 and 6, I inclosethe rows of windows with ilues M, whichcommunicate With the interior of the rooms ot the building through theopenings t, and

also with a chimney, D, suitably located. I

have found that this is the only ei'ective mode ot' preventing theescape of the gases from a siuglewalled building, as the partial vacuumin the 'iues M tends not only to exhaust the vapors from the rooms ofthebuilding, but to in duce a slight current of air inward through thejoints ofthe windows, all tendency of the gases to escape therefrombeing thereby prevented.

I claim as my invention- 1. A building having double Walls or ues,inclosing passages which communicate with the interior of' the apartmentor apartments in the building, with the Windows in the outer wall of thesaid ney, I, as set forth.

2. The combination of the chimney l with an apartment having a doubleceiling, the inl Errori.
